There is a discussion about a WebExtensions API to hide the tab bar: https://bugzilla.mozilla.org/show_bug.cgi?id=1332447

You can move the sidebar from left to right by Firefox's built-in option. See the sidebar header and click the label "Tree Style Tab", then you'll see a list of switchable sidebar panels and the "Move Sidebar to Right" option.
